IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 172,838, dated February 1, 1876; application filed December 6, 1875. i

To all whom it may concern:

Be it known'that I,JAM'ES M. WHITE, of

Springfield, in the county of Clarke and State of Ohio, have invented a new and valuable Improvement in Harrows; and I dohereby declare that the follow ng is a full, clear, and

Y exact description of the construction and oper- 'ation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon. I

Figure 1 of the drawing is a representation of a plan View of my improved harrow. ,Fig.

2 is an-end view, showing the two sections folded upon each other. Fig. 3 is an enlarged view, showing the manner of connecting the two sections; Fig. 4, an end view ojt'; Fig. 3.-

This invention has relation .to that class'of harrows'iu which the two sections are capable'of being folded upon each other and the object of the present iuvention is to produce a barrow perfect in its operation, simplefin itsconstruction, and at the sametime dura- Me and not easily gotten out of repair and the'invention consistsiu the com binatlon and .arrangementof the several parts hereinafter described, and subsequently pointed out in.

the claim.

In the accompanyingdrawings, A B represent thetwo sections of my mproved barrow, consisting of the cross-beams a, to which are securedthe teeth I To the under side of; the beams aare bolted or otherwise secured diagonal braces c, -togive them additional strength and. prevent any lateral displace went from the strain thereon. Braces d are secured, by suitable bolts, to the several beams a of section A, near-their ends, holding themrigidlyin their relative position. The" inner ends o f'these braces dare bent around to form elongated" loops 6, after whichv the metal is turned under the beam, forming ashort brace, f,' thereby 'securely clamping the beam and holding it in afrigid manner, as the strain upon the inner beam, is much greater f.

in proportion to the others. The section B] "has similar braces g g, the innerends'being bent around toform eyes h,'for the reception of a looking or connectingrod, G. The continuation of the braces I!) also passes around and under the beam, forminga brace, 1;, similar to the brace f. The two sections A3 are coupled-rogetherby the connecting-rod Q,the same passing through the eyes haud elongated loops 6, the rod being prevented; from 1 vpulling out-bya key, j, fitting in a slot in the end'of the rod.

A harrow constructed accordingtemyim -vention will be found very etfectivezin-its pury pose, as it admitsof a vertical vibratory mo-j tion to accommodate itself to the irregularities in the surface of the ground, insuring'all the teeth acting at the same'time; also, the

elongated loops with the conuecting-rod'allow' I either section A B to be folded upon ieach J otherwithout the necessity of stopping the team. The several braces and their manner of con w nection to the beams make a very strongiand, durable harrow,that will stand the rough use to which such devices are subjected without- 1. the danger ol'becoming injured.
